Abstract Background Accidental damage of tricuspid apparatus remain known complication of TLE procedure but our knowledge is limited due lack of separate analysis in the literature. Purpose The goal of this study was analysis of the appearance of lead extraction related tricuspid valve dysfunction using trans-chest and trans-oesophageal echocardiography. Methods Between March 2006 and December 2018 we performed 2900 TLE procedures using conventional mechanical sheaths in 1760 male and 1140 female patients (mean age 66.6y). 4811 leads (mean implant duration 91.5 months) were removed due to non-infective indications in 65.3%. Full radiological success was obtained in 95.7% procedures, partial in 4.0%, clinical success in 98.0%, full procedural success in 96.1%. Major complications (MC) appeared in 8 (1.8%). Results Results are presented in the table Conclusions TLE using conventional mechanical sheaths is effective. Tricuspid valve dysfunction different degree is frequent finding in candidates for TLE. TLE procedure brings risk (7.2%) of different degree damage of tricuspid leflet (significant in 1.5%) or even chordae tendinae (4%). Patients with severe lead extraction related tricuspid valve dysfunction needs exact follow-up and some of them can be candidates for cardiac surgery. On the other hand in not so rare cases of lead related tricuspid valve dysfunction – lead removal/replacement can to bring improvement of tricuspid valve function (6.1%).

Abstract Aims  Commonly, a dysfunctional defibrillator lead is abandoned and a new lead is implanted. Long-term follow-up data on abandoned leads are sparse. We aimed to investigate the incidence and reasons for extraction of abandoned defibrillator leads in a nationwide cohort and to describe extraction procedure-related complications. Methods and results  All abandoned transvenous defibrillator leads were identified in the Danish Pacemaker and ICD Register from 1991 to 2019. The event-free survival of abandoned defibrillator leads was studied, and medical records of patients with interventions on abandoned defibrillator leads were audited for procedure-related data. We identified 740 abandoned defibrillator leads. Meantime from implantation to abandonment was 7.2 ± 3.8 years with mean patient age at abandonment of 66.5 ± 13.7 years. During a mean follow-up after abandonment of 4.4 ± 3.1 years, 65 (8.8%) abandoned defibrillator leads were extracted. Most frequent reason for extraction was infection (pocket and systemic) in 41 (63%) patients. Procedural outcome after lead extraction was clinical success in 63 (97%) patients. Minor complications occurred in 3 (5%) patients, and major complications in 1 (2%) patient. No patient died from complication to the procedure during 30-day follow-up after extraction. Conclusion  More than 90% of abandoned defibrillator leads do not need to be extracted during long-term follow-up. The most common indication for extraction is infection. Abandoned defibrillator leads can be extracted with high clinical success rate and low risk of major complications at high-volume centres.

Abstract OBJECTIVES Our goal was to analyse all lead extraction procedures (transvenous or open surgery) performed in our centre and the short- and long-term follow-up data from these patients. METHODS All lead extractions performed from 2008 to 2017 were retrospectively reviewed for patient characteristics and indications for device implantation; indications for lead extraction; techniques used; peri- and postprocedural complications and short- and long-term follow-up data. RESULTS A total of 159 patients (282 leads) were included [age 70 (62–78) years; 72% men]. The median follow-up time was 57 (25–90) months. Patients with lead explants were excluded. The most common indication for lead removal was infection (77%). A surgical approach was necessary in 14 patients (9%) owing to unsuccessful transvenous removal (n = 3), large vegetation in the lead (n = 4), concomitant valvular endocarditis (n = 2), other indications for open surgery (n = 4) and complicated transvenous removal (n = 1). Removal was tried for 282 leads. Of those, 256 were completely removed. Clinical success was achieved in 155 individual patients (98%). Complications occurred in 6 patients: 3 persistent infections, 1 stroke and 2 blood vessel ruptures. The procedure-related mortality rate was 2% (n = 3). CONCLUSIONS Lead removal was associated with a high success rate and low all-cause complication and mortality rates. Emergency surgery because of acute complications was rare, and open-heart surgery was most frequently elective and not associated with a worse outcome.

Abstract Background Accidental damage of tricuspid apparatus is known complication of TLE procedure risk factors of this complication remain unknown. Purpose The goal of this study was to search factors which can predict damage of tricuspid apparatus during TLE. Methods Between 2006 and 2018 we performed 2002 TLE procedures using conventional mechanical sheaths. 3366 leads (mean implant duration 95,2 months) were removed due to non-infective indications in 62,0%. Tricuspid valve function was examined with preoperative and post-operative TTE and during monitoring of procedure. Patients with incomplete TV function evaluation were excluded from the study. Three groups of patients were compared Results TLE procedure brings risk (7%) of different degree damage or tricuspid leflet or even chordae tendinae (2%). The detailed results are presented in the table. Conclusions TLE using conventional mechanical sheaths is effective but brings risk of extraction related tricuspid valve dysfunction. Main risk factor of this complication seems to be implant dwell time, number of leads presence of abandoned leads and lead loop in the heart remaining in conflict with tricuspid valve.

Background: Lead-related tricuspid valve dysfunction (LDTVD) has not been studied in a large population and its management remains controversial. Methods: An analysis of the clinical data of 2678 patients undergoing transvenous lead extraction (TLE) in years 2008–2021 was conducted, with a separate group of 119 patients with LDTVD. Potential risk factors for LDTVD, improvement in valve function, and long-term prognosis after TLE were assessed. Results: LDTVD was diagnosed in 4.44% of patients referred for lead extraction due to different reasons. The most common mechanism of LDTVD was propping upward or clamping down the leaflet by the lead (85.71%). The probability of LDTVD was higher in female sex, patients with valvular heart disease, atrial fibrillation, heart failure, large right ventricle and high pulmonary artery systolic pressure, the presence of only pacing lead, and in case of collision of the lead with tricuspid valve and adhesion of the lead to the heart structures. The prognosis of patients with LDTVD was worse, however, patients with improved valve function after TLE showed a significantly better long-term survival. Conclusions: Lead dependent tricuspid valve dysfunction is a potentially serious condition that requires thorough diagnostics and thoughtful management. The risk factors for LDTVD are primarily related to the course of the lead and its adhesion to the heart structures. Improvement of tricuspid valve function after TLE is observed in 35.29% of patients Patients with LDTVD have a worse long-term survival, but the improvement in valve function following TLE contributes to a significant reduction in mortality.

Abstract Background The guidelines suggest close co-operation between TLE operating team and cardiac surgery and its key role in the management of life-threatening complications remains unquestionable. But the role of cardiac surgeon seems to be much more extended. Purpose We have analysed the role of cardiac surgery in treatment of patients undergoing TLE procedures. Methods Using standard non-powered mechanical systems we have extracted ingrown PM/ICD leads from 3207 pts (38,7% female, average age 65,7-y) during the last 14 years. Non-infectious TLE indications were in 66,4% of patients. 46% had PM DDD system, 19% PM SSI, 22% ICD, 9% CRT, 4% other systems. In 12% of patients abandoned leads were found. 8% of patients had one lead, 54% - two, 15% - three and 4% - 4–6 leads in the heart. An average dwell time of all leads was 91,5 mth. The lead entry side was left in 96% of patients, right in 3% and both – 4%. Results Procedural success 96,1%, clinical success - 97,8%, procedure-related death 0,2%. Major complications appeared in 1,9% (cardiac tamponade 1,2%, haemothorax 0,2%, tricuspid valve damage 0,3%, stroke, pulmonary embolism <1%). Conclusions Rescue cardiac surgery (for severe haemorrhagic complications) is still the most frequent reason of surgical intervention (1,1%). The second area of co-operation includes supplementary cardiac surgery after (incomplete) TLE (0,8%). The third one is connected with reconstruction or replacement of tricuspid valve, which can be affected by ingrown lead or damaged during TLE procedure (0,5%). Implantation of the complete epicardial system during any surgical intervention (rescue or delayed) should be considered as a supplementation of the operation (0,65%). Some of patients after TLE need implantation of epicardial leads for permanent epicardial pacing (0,6%) and some only left ventricular lead to rebuild permanent cardiac resynchronisation (0,5%). The single experience of large TLE centre indicates the necessity of close co-operation with cardiac surgeon, whose role seems to be more comprehensive than a surgical stand-by itself.

Background : Symptomatic vertebral artery stenosis (VAS) has a five-year stroke risk of 30%–35%. Mortality associated with posterior circulation (PC) strokes is high, ranging from 20%–30%. Surgical revascularization is rarely performed due to high morbidity and mortality. Endovascular revascularization with stents offers a potential treatment option for these patients. Methods : One hundred nine patients (116 arteries, 70% male) underwent stent placement for extracranial (91%) and intracranial (9%) VAS from 1995–2006. Symptoms included vertigo (63%), visual changes (31%), syncope (11%), ataxia (7%), and drop attack (5%). Four patients had asymptomatic critical stenosis. Sixty-one patients (56%) had bilateral VAS, 74 patients (69%) had concomitant carotid disease, and 43 patients (39%) had a prior stroke. Procedural success was defined as residual stenosis of ≤ 20% without peri-procedural stroke or death. Clinical success was defined as procedural success with symptom resolution. Restenosis was defined as angiographic narrowing within the stent of ≥ 70% or > 50% with recurrent symptoms, or evidence of severe stenosis on non-invasive imaging (ultrasound, CT, or MR). Results : Procedural and clinical success was achieved in 108 (99.1%) and 95 (94.3%) patients, respectively. At one year, follow-up was obtained in 91 patients (83.5%), 6 patients (5.5%) had died, 5 patients (5.3%) experienced a PC stroke, and 47 patients (43.1%) underwent repeat angiography and/or non-invasive imaging. Eighty-seven of the 91 patients were initially symptomatic, 69 (79.3%) of which were symptom-free at one year. Three of those that had recurrent symptoms never achieved clinical success, 9 had developed restenosis, and 7 underwent successful re-intervention. At median follow-up of 31 months (lower and upper quartiles of 13.0 and 51.8 months), 72.5% were alive and 71.6% remained symptom-free. Conclusion : Our data demonstrates that stenting for VAS can be successfully performed in 99% of patients without peri-procedural stroke or death and is associated with durable symptom resolution in approximately 80% of patients at one year. In these high-risk patients, endovascular therapy for symptomatic VAS appears to be safe and effective at relieving symptoms.

Introduction: The purpose of the current study was to investigate the periprocedural and long-term outcomes of stent implantation for de novo subclavian artery (SCA) disease. Material and Methods: We retrospectively investigated consecutive patients with de novo SCA lesions undergoing elective endovascular therapy procedures at our center between April 2004 and September 2015. All patients were included in the analyses of periprocedural outcomes, including procedural and clinical success. Subsequently, patients who completed the clinical follow-up and were assessed with brachial systolic pressure differences between the diseased and the contralateral arms, or angiographic stenosis, after stent implantation with procedural success were included in the analyses of long-term outcomes, including primary patency. Results: There were 62 patients (median 71.0 years, interquartile range 65.3-76.0 years; 45 men) with 62 de novo SCA lesions included in the analyses of periprocedural outcomes. There were 46 stenoses (74.2%) and 16 occlusions (25.8%). Our results indicated high procedural success rates for overall (95.2%), stenotic (97.8%), and occlusive (87.5%) lesions. Similarly, high clinical success rates were observed for overall (91.9%), stenotic (93.5%), and occlusive (87.5%) lesions. The median follow-up time was 6.0 years (interquartile range, 2.6-8.3 years). There were 48 patients with 48 de novo SCA lesions included in the analyses of long-term outcomes. Primary patency estimates were 97.7% (1 year), 97.7% (3 years), 93.1% (5 years), and 87.6% (7 years). Also, we observed a high estimate for freedom from reintervention for the target vessel (93.8%). Conclusion: Stent implantation for de novo SCA disease can be performed successfully and safely with favorable periprocedural and long-term outcomes.

Background: A lead-reactive fibrous capsule (FC) identified by ultrasounds as an atrial or ventricular lead thickness of more than 1 mm above the vendor-declared lead diameter (TL) and its local fibrotic attachment to the cardiac wall (FAC) have never been investigated in vivo, so their relationship with post-extraction masses (ghost) is not known. Methods: Intracardiac echocardiography (ICE) was performed twice during the same extraction procedure in 40 consecutive patients: before and immediately after infected lead extraction Results: The ghost detection rate was high: 60% (24/40 patients); ICE could identify both TL and FAC, TL being noted in 25/40 (62%) patients and FAC in 12/40 patients (30%). Both TL and FAC were significantly associated with ghosts (p < 0.001 and p = 0.002, respectively), but TL had a higher prediction power. The specificity was similar: 94% (15/16) and 100% (16/16), respectively, but TL showed a much higher sensitivity: 100%, (24/24) vs 50% (12/24) (p = 0.016). The ghost group did not show a higher event rate in the follow-up (mean follow-up time = 20 ± 17 months). Conclusion: ICE is able to evaluate both TL and FAC in vivo; ghosts are mostly benign remnants of fibrotic lead capsule cut off during extraction and retained inside the heart by FAC.
